Abstract

La présente invention concerne un évaporateur, par exemple, pour la production d’eau fraîche à partir d’eau de mer et similaire, ou pour la concentration d’une solution aqueuse, capable de simplifier la construction et la maintenance d’un coefficient élevé de transfert thermique et de réduire le temps et les efforts d’assemblage. Une unité de transfert thermique (5) comprenant deux plaques de transfert thermique (5a) disposées l’une au-dessus de l’autre est installée. Une pluralité de passages d'écoulement de fluide (5b) formés en exposant les plaques de transfert thermique à une déformation concave sont disposés de façon à s’étendre sensiblement parallèlement les unes aux autres. Une pluralité des unités de transfert thermique sont disposées sous forme stratifiée à l’intérieur d’un conteneur scellé hermétiquement (1) de sorte que les passages d'écoulement de fluide dans les unités de plaques de transfert thermique s’étendent dans une direction horizontale. Des matériaux d’étanchéité élastiques flexibles (7,8,9) sont introduits entre les deux extrémités mutuelles dans les unités de transfert thermique, et la surface externe de chacune des unités de transfert thermique est cloisonnée depuis l’intérieur de chacun des passages d'écoulement de fluide dans chaque unité de transfert thermique par le matériau d'étanchéité. Un liquide à évaporer est injecté sur la surface externe des unités de transfert thermique, tandis que la vapeur de chauffage est injectée dans les passages d'écoulement de fluide des unités de transfert thermique.
